short screenrecord with obs, because these lines are not visible on screenshots

SUMMARY
***
Lines around windows popups and sometimes randomly on plasma-wayland. This seems to be related to either masking/anti aliasing/shadows, as the same lines are visible on auto-hide panels. This also appears inconsistently around popups(window previews, volume change etc.)
***


STEPS TO REPRODUCE
1. Use plasma wayland
2. Use scaling (some lines are still visible without scaling, but more frequent with scaling, for instance around autohide panels)

OBSERVED RESULT
Flickering lights appear.

EXPECTED RESULT
Normal rendering.
